microwave oven magnetrons are the heart of any microwave, but how do you know if yours is still kicking? 🤔 First, check for any physical damage like cracks or burn marks. If it looks fried, it probably is! 🔥 Next, listen closely when the microwave is running. A buzzing sound could indicate trouble. 🐝 Also, pay attention to cooking performance. If your food isn’t heating evenly, it might be time to inspect the magnetron. 🔪 Lastly, use an ohmmeter to test its resistance. The reading should fall within a specific range—consult your manual for exact numbers. If it’s off, consider replacing it. 💡 Regular maintenance keeps your kitchen hero humming along smoothly! 🏡✨
